Description #
Modula-2 is a statically typed, procedural programming language designed for system and application programming. It emphasizes modular programming with strong type safety and supports structured programming concepts.
History #
Developed by Niklaus Wirth in the late 1970s as a successor to Pascal, Modula-2 introduced modules to facilitate separate compilation and code reuse. It was widely used in academia and embedded systems and influenced later languages like Oberon.
Hello World Code #
MODULE HelloWorld;
FROM InOut IMPORT WriteString, WriteLn;
BEGIN
WriteString("Hello, World!");
WriteLn;
END HelloWorld.How to Run #
Option 1: Online
Use online compilers like OnlineGDB Modula-2.
Option 2: Local
- Install a Modula-2 compiler like GNU Modula-2 or XDS
